Do you mean Primary keys?

I'm guessing you mean PostgreSQL ? :-)

pgAdmin hides indexes that implement other types of object. The fact
that a unique constraint or a pkey is actually an index is an
implementation detail and is unimportant to the user, in the same way
that it is unimportant to show foreign keys as sets of triggers and
views as rules as they really are.
